McIntosh introduces speakers, equalizers
McIntosh, the Binghamton. New York manufacturer. has a new line of speaker systems which range from $312 for the MC IC, left, to $1.012 for the ML 4C, and which are or Mediterranean cabinet styles. Wide-angle dispersion of midrange and highs. and full. accurate reproduction of bass is claimed for all models. The company also is offering two versions of an "environ mental equalizer"-the MQ 102 corrects for left- and right-bass differences in a stereo system: the larger Model MQ 101. shown here, corrects the bass and the middles and highs too.
Two new receivers from Sony
Sony is offering two new stereo FM/AM receivers, the Models STR-6065 and STR-6055, priced respectively at $399.50 and $299.50. The sets are similarly styled, but the STR-6065 offers higher output power and greater FM sensitivity. Manufacturer's specs rate the STR-6065 for 70 watts per channel continuous power at less than 0.2 percent distortion, with an IHF sensitivity of 2.2 microvolts.
The STR-6055 is rated for 40 watts per channel continuous power at less than 2 per cent distortion with an IHF sensitivity of 2.6 microvolts. Both units offer a full complement of features and con trols, including front-panel speaker selector, dual concentric tone controls, headphone jack, and an auxiliary (high-level) front-panel input for quick or temporary patching-in of an external source. The STR-6065 is shown here.
Kenwood announces 3-way speaker system
Kenwood's first speaker system. the KL-5060,incorporates a 12-inch free-edge woofer, a 6 1/2-inch midrange, and two horn-type tweeters. Crossovers are at 600 Hz and 5,000 Hz: a tone selector can adjust midrange and highs. The speakers are enclosed in an oiled walnut cabinet (with metal grille) that stands two feet high. Weight: 44 lb. Price: $139.95.
--------- H-K delivers Citation Eleven preamp
This second model in Harman-Kardon's Citation line was first announced some months ago and is now being shipped to dealers. The Model Eleven preamp provides both impressive specifications and versatile operating controls. The $295 preamplifier ($35 extra for oiled walnut enclosure) has abandoned normal tone controls, which cover a broad frequency spectrum, in favor of five calibrated slide-con trolled "audio equalizers." each of which permits adjustment of a portion of the audio band. A special defeat switch removes these equalizers from the circuit. A full array of controls includes high and low filters, and a selector for choosing one or both of two pairs of stereo speaker systems or two sets of low-impedance headphones.
Manufacturer's specs claim frequency response within =0.5 dB from below 5 to 125,000 Hz. Residual noise level is given at 90 dB below rated output of 6 volts.
Stylus force gauge from Shure A new stylus force gauge, claimed accurate within 0.1 gram up to 1 1/2 grams, is being marketed by Shure Brothers for $4.95. Designed as a positive counterweight balance, the Model SFG-2 can measure stylus pressures up to 3 grams. As shown in the accompanying photo.
the counterweighted end of the gauge is aligned with the spindle. and the tone arm is placed over the opposite end with the stylus in a narrow groove. The measurement is then read on a scale.
EPI delivers baby speaker EPI has announced the Model 50, a miniature (13 by 10 by 8 inches) $55 version of their larger bookshelf speakers, which consists of two acoustic-suspension drivers plus crossover in a solid walnut box.
Frequency response is given at 50 Hz to 18,000 Hz ( ± 3 dB), and the system needs a minimum of 14 watts rms.
Mono preamp for tape recorders Telex offers, in its new RP-84, a preamplifier specifically designed for recording and playback use with two- or three-head tape recorders. Because the adjustable bias oscillators can be synchronized when using several of the mono RP-84s, they can be used for multichannel setups-for instance in converting a stereo deck for four-channel use.
A high-impedance phone jack and VU meter are incorporated into the Telex unit, which is priced at under $145. A rear-panel selector switch sets up the front-panel slow/fast switch to choose 1 and 3 3/4, 3 3/4 and 7 1/2, or 7 1/2 and 15 ips equalizations.
The preamp is rated at 30 Hz to 18,000 Hz ± 3 dB at 7 1/2 ips.
Hartley offers under-$100 speaker system Hartley-Luth's Zodiac II is, according to the manufacturer, its first full-range system below $100. Hartley claims the two-speaker system provides a response range of 40 Hz to 18,000 Hz at less than 1.5% distortion. It requires at least 15 watts of power per channel. Dimensions are 18 by 11 1/2 by 8 1/2 inches and it weighs 16 lb. A slightly larger and heavier three-speaker system for $135, the Zodiac III, is also available. Both come in either teak or rosewood.
=====================
Vintage magazine ADs:
Controls are of the Baxandall type. And there are high filters, loudness contour and tape monitoring switches. All the controls work on the front channels alone, the rear channels alone, or on all four simultaneously.
The Fisher 701 is the first 4-channel stereo receiver. But we're predicting it will be the first of many.
The Fisher 450-T, $399.95.
The Fisher 450-T is similar, in many respects, to the 500-TX we describe above.
It's got almost as much power (the 450-T has 180 watts), and most of the tuning convenience: the 450-T has AutoScan, plus flywheel tuning. And the $399.95 price includes remote-control AutoScan.
The FM section, with 2.0 micro volts sensitivity, will bring in almost as many stations as the 500-TX's FM section, and with the same characteristic ally Fisher sound: clean and natural, at all frequencies.
The man who wants to tune the easy way, electronically, more accurately than with the aid of a meter, a light or a 'scope, should start by looking at the Fisher 450-T.
Shown in photo at right: The Fisher 500-TX, plus a pair of the world's finest bookshelf speakers (the 4-way Fisher XP-9C's, $199.95 each), Fisher's best headphones (the Fisher HP-100, $39.95) and the new Fisher RC-80 stereo cassette deck with Dolby noise reduction unit built in ($199.95).
...when the easy way is more accurate.
Now there are three Fisher receivers that give you push-button electronic tuning without moving parts, plus remote control.
Tuning with a knob is not only harder than tuning with a button, it's also less accurate.
Because Fisher's exclusive AutoScan" automatic push-button electronic tuning is more accurate than knob tuning, even when you use a meter or a 'scope.' We quote Audio magazine:
"AutoScan is probably more accurate in tuning to center of desired channel than can be accomplished manually." AutoScan (as well as our Tune-O-Matic push-button memory tuning) is a purely electronic tuning system.
There are no moving parts. Instead, devices called varactor diodes are used to lock in stations at their most distortion-free tuning point. Our engineers estimate that tuning accuracy is ten times greater with AutoScan than is possible with manual tuning.
Here's how you tune with AutoScan.
Press one of the AutoScan but tons, and the receiver automatically tunes to the next station on the dial.
You can tune one station at a time, or whisk up and down the dial, by pressing a continuous-advance button.
For added convenience, a re mote control unit lets you wo7k the AutoScan from your favorite chair.
Of course, for the psychological benefit of those who still want to tune manually, Fisher receivers all have ultra-smooth flywheel tuning, complete with an accurate tuning meter. And, in addition to AutoScan automatic tuning and manual tuning, the Fisher 500-TX has still another tuning convenience called Tune-O-Matic.
A button for each of your favorite FM stations.
Tune-O-Matic is another form of diode tuning. It has no moving parts.
and works completely electronically, just like AutoScan. However, Tune-O Matic is actually a simple compute with a memory. You program each of the Tune-O-Matic push buttons with the frequency of a favorite FM station. After that, you just push the button that corresponds to the station you want to hear, and that station will be locked in immediately. Perfectly tuned to center-of-channel, of course.
The Fisher 500-TX, $499.95.
This 200-watt AM/FM stereo receiver comes with AutoScan, Tune O-Matic and a flywheel tuning knob.
Remote control tuning (AutoScan) is available as an option at slight additional cost.
This is probably the world's most advanced 2-channel stereo receiver.
The FM tuner section is not only extremely sensitive (IHF sensitivity, 1.7 microvolts) but extremely selective as well, thanks to special 4-pole crystal filters that help us achieve up to six times better selectivity in production-line receivers than competitive models we've tested.
And with 200 watts of clean power you'll be able to drive a remote pair of speaker systems, as well as a big, power-hungry main stereo system, complete with a third, center-channel speaker.
The Fisher 701, $699.95.
The 701 is the world's first and only 4-channel stereo receiver. And it's worth its price just to be able to play one of the growing number of 4-channel stereo tapes now on the market.
But the 701 is more than a 4-channel stereo receiver. It's also one of the world's finest 2-channel receivers.
So while you're waiting for 4-channel to gain the acceptance the experts predict for it, you can still enjoy slate-of-the-art 2-channel stereo (or even mono, for that matter).
The 701 incorporates Fisher tuning conveniences, including AutoScan, remote-control AutoScan, and ultra-smooth knob tuning.
The FM section, with five integrated circuits, has a sensitivity of 1.7 microvolts.
The AM section approaches FM in quality.
As for power, the Fisher 701 is hard to beat. It has 250 watts, which is enough to drive not one, but two sets of tour speakers (one main, one re mote). And it drives them without strain.
The controls are as sophisticated as the rest of the 701. Volume controls are of the sliding type, similar to the kind you find on the control panel in a broadcast studio. The bass and treble

It takes a lot of guts to say a new stereo cassette deck is the greatest ever made.
Wollensak can say it.
The new Wollensak 4750 stereo cassette deck brings true hi-fidelity to cassette listening.
Here's why: It has one of the lowest wow and flutter characteristics of any deck available. The precise heavy duty tape transport mechanism is considered by independent audio experts to be the finest in the industry.
A mechanism that includes the only full-size flywheel and capstan avail able to assure constant tape speeds and eliminate sound distortion.
Record-playback frequency response is truly exceptional: 60-15,000 Hz, +- 3 db. Fast-forward and rewind speeds are about twice as fast as any other.
A massive, counter-balanced bi peripheral drive means years of dependability. Interlocked controls allow you to go from one function to another without first going through a stop or neutral mode. The Wollensak 4750 features end-of-tape sensing which stops the cassette, disengages the mechanism and prevents unnecessary wear. The Wollensak "Cassette Guardian" automatically rejects a stalled cassette in play or record position. The 4750 complements your present component system by providing cassette advantages. American designed, engineered and built. Styled in a hand-rubbed walnut base with Plexiglass' smoked dust cover.
All of these features add up to the truest stereo sound with reel-to-reel quality from a stereo cassette deck.
Become a believer. Hear and compare the new Wollensak 4750 deck at your nearby dealer.

THE FIRST CROWN PREAMPLIFIER
What would happen to a preamplifier design, if the design engineer could free himself from stereotyped ideas and start fresh with only a list of customers' re quests? Well, at CROWN that has just happened, and the result is the IC150, an exciting "new concept" control center with simplified circuitry, controls that are easy to understand and use, several exclusive features, unsurpassed quality, and- to top it all off--a lower price tag.
Crown Engineers discovered that pre-amp switches don't need to pop . . .
that there is something better than the stereo mode switch . . .
that the phono preamp can be dramatically improved . . . and, that by using IC's, a versatile high-quality, advanced-performance preamplifier can be priced to beat inflation.
Of course, the true uniqueness' of such an innovative design cannot be appreciated by reading about it. The only answer is to experience the IC150 yourself. Let us tell you where Crown's "new concept" is being introduced in your area. Write today for a list of locations.
World's quietest phono preamp Infinitely variable stereo panorama control Solent switching and automatic muting at turn-on and turn-off Integrated circuit modules Industry's lowest distortion levels Full range tone and loudness controls Guaranteed phase response 3-year parts and labor warranty Will drive any amplifier $239. walnut enclosure $33 O15L7 Ask your dealer also about Crown's new companion D150 power amplifier, which delivers 200 watts IHF output at 8 ohms or 350 watts at 4 ohms.
No amp in this power range--however expensive--has better frequency response or lower hum, noise or distortion. It offers performance equal to the famous DC300, but at medium power and price. It's worth listening into!

NEW, TRANSPARENT AND BEAUTIFUL.
ADC's brand new 450A is a "high transparency" speaker system for the perfectionist who wants to own the best bookshelf system money can buy.
This two-way system avoids the use of complex crossover networks and the resultant phase distortion. By enabling the majority of the audio spectrum to be radiated by the high frequency unit, we achieve essentially a "single point source". The low frequency driver is then left to do the demanding but un complicated job of reproducing the low and basically non-directional portion of the audio spectrum.
The result is an extremely transparent true-to-life bookshelf speaker system you must hear to appreciate.
ADC 450A SPECIFICATIONS Type ... Full-sized bookshelf.
Cabinet ... Oiled Walnut.
Dimensions ... 25" H x 14" W x 12 3/6" D.
Weight ... 50 lbs. each.
Frequency Response ... 25 Hz to 30 kHz ± 3 dB (measured in average listening room).
Speakers (2) ... 3/4" "point source" wide range tweeter and 12" high compliance woofer.
Nominal Impedance ... 6 ohms (for optimum performance from transistorized amplifiers).
Power Required ... 10 watts RMS minimum.

Never before have so many received so much for so little.
You can't blame people these days if they want to get the most for their money. Maybe that's why the Pioneer SX-990 is so popular. When you com pare its specifications and features with similar priced AM-FM stereo receivers, and then listen to its performance, you become a believer.
For instance, with sensitivity at 1.7 microvolts. the SX-990 brings in the most timid FM stations and makes them sound as though the,-were just around the corner. Or, if you live where FM stations are a hairline away from each other on the dia , it delivers clear, interference-free reception.
Small wonder, with a capture ratio of 1dB.
Pioneer has invested the SX-990 with 130 watts of IHF music power (28--28 RMS at 8 ohms). And it's all clean and smooth with a cw 0.5% harmonic distortion at rated output.
Its top quality circuitry includes four IC's and a special low-noise FET.

The new KLH Thirty-Two is the best speaker you can buy for the money.
Bravado has never been our bag.
But after carefully comparing the new model Thirty-Two with our competitor's best-selling loudspeaker, we're going to break our rule.
Our product is superior.
You see, the Thirty-Two sounds like a very close relative of our now famous Model Six.
With good reason.
It's designed like a Six. It's built like a Six. And it shares many of the Six's finest listening qualities. Bass response that curls your toes. A mid-range that seduces you with its smoothness. And an overall sound quality that finally puts an end to listening fatigue.
But the Thirty-Two not only sounds like an expensive speaker, it looks like one, too. It is unquestionably the suggested retail price. Slightly higher in the west, best looking loudspeaker in its price range.
The price? Almost as amazing as the sound. Just $47.50 ($95 the pair).1 Make sure you hear-and see-the new KLH Thirty-Two soon. And compare it with the best-known speaker in its price range. We are sure you will agree that there's never been anything like it for the money.
Anybody's money.

Altec's new 714A receiver.
It's built a little better.
FREQUENCY KHz, HD, Harmonic Distortion Curve at 44 watts R .M .S . output.
With 44/44 watts RMS power at all frequencies from 15 Hz to over 20 KHz (at less than 0.5% distortion). Most receivers meet their power specifications in the mid-band but fall way short at the critical low and high frequencies. The above curve shows the typical low distortion at all frequencies from the new 714A receiver at 44 watts RMS per channel. For comparison purposes, we also rate the 714A conservatively at 180 watts IHF music power at 4 ohms. This means that the 714A will handle every thing from a full orchestration to a rock concert at any volume level with power to spare.
CRYSTAL FILTER
With 2 crystal filters and the newest IC's. Ordinary receivers are built with adjustable wire-wound filters that occasionally require periodic realignment.
And unfortunately. they are not always able to separate two close stations. So we built the new 714A with crystal filters.
In fact, 2 crystal filters that are individually precision aligned and guaranteed to stay that way. To give you better selectivity. And more precise Lining. The new 714A also features 3 FET's and a 4 gang tuning condenser for high sensitivity.
Built a little better.

Have the high notes on your records become only a memory? When Jascha Heifetz plays a high note on your favorite violin recording, are you actually hearing it? Or are you just remembering it? That's something to think about when you consider how many hundreds of dollars you've invested in your records.
And what can happen when you play them.
As soon as the stylus touches down in the groove, a running battle begins. The stylus is violently tossed up, down and sideways, thousands of times a second.
These motions are either producing beautiful high notes, or expensive memories. It all depends on the tonearm.
How the tonearm should work.
If the tonearm does its various jobs properly, your records can last a lifetime.
So we think it is worth investing a few minutes of your time to understand the essentials of what a tonearm is supposed to do.
The tonearm must apply just the right amount of pressure to the stylus, keep this pressure equal on both walls of the groove, and follow the stylus without resistance as the groove spirals inward.
Then the stylus will be able to respond freely to all the twists and turns in the record groove, without digging in or chopping away.
And the pending four-channel records are likely to require the stylus to perform even more complex gyrations.
It takes some engineering.
Dual tonearms do all these jobs extraordinarily well. For example, the tonearm of the 1219 works like a gyroscope. It pivots up and down on one ring, left and right on another.
And all four pivot points are identical. This suspension system is called a gimbal. And no other automatic tonearm has a pivot system like it.
in ring gimbal system of Dual 1219.
Arm pivots vertically from inner ring, horizontally 'rpm outer ring. Al four suspension points have identical low-friction bearings.
It takes extraordinary precision.
Every stylus is made to apply even pressure on the groove walls. But during play, the groove pulls the stylus against the inner wall. Better tonearms have a special setting to compensate for this "skating" effect.
Anti-skating system of Dual 1209 and 1219 has separate calibrations for elliptical and conical However, for an anti-skating system to be effective, bearing friction must not only be low, but consistent. If you con imagine fifteen thousandths of a gram, that's the maximum bearing friction of the 1219. Guaranteed.
And some other angles.
Apart from preventing record wear, tonearm design should prevent distortion.
This largely depends on the angle of the stylus in the groove. Which depends in some cases on tonearm design, in others on the way the cartridge fits into the tonearm head.
The longer the tonearm, the lower-he tracking error.
The 1219 is 834" from pivot to stylus tip, longest of all automatic tonearms.
The angle of the stylus in 1215 VC,' the groove alters during play depending on whether you are playing one record or a stack. The Dual 1219 is an exception because its tonearm can be set for the correct angle in either single or multiple play.
Mode Selector of Dual 1219 lowers tonearm base for single play. Stylus tracks at correct 15° angle.
The professionals’ choice.
Dual turntables have been the choice of professionals for many years because of their precision, ruggedness and simplicity of operation. And not always the most expensive Dual, either.
If you'd like to know what independent test labs say, we'll send you complete reprints of their reports. Plus an article on what to look for in record playing equipment reprinted from a lending music magazine.
But if you're already convinced and can't wait, just visit your authorized United Audio dealer and ask for a demonstration.
Dual automatic turntables are priced from $99.50 to $175.00. When you think about it, that's not very much to pay to keep your records from becoming a costly memory.

The unusually high price of the new Sony 6200 receiver is a come-on. For once you know it, you can hardly resist the temptation to hear it perform and justify its lofty price. And once you hear it perform, you'll have to own this superb component.
The real joy of the 6200 lies in its performance. Balanced positive and negative power supplies permit direct coupling all the way through to the speakers for unusual clarity. There is power to spare by whatever measure: 360 IHF watts into 4 ohms, 70+70 watts continuous power into 8 ohms with both channels driven; a minimum of 60+60 at all frequencies from 20 to 20,000 Hz.
FM performance is equally distinguished. The FET front end raises the sensitivity to its theoretical limit (1.2 uV for 20 dB quieting; 1.8 uV IHF), while retaining the ability to handle strong local stations without over load and spurious response. Solid state i.f. filters ensure that the same superb performance you hear today, you'll enjoy many years later; the receiver never needs re alignment.
Throughout, the accent is on pleasure. the silky feel of the flywheel tuning action. The precision and stability of the 6200's tuning: locate the frequency you want on the long, linear dial with the power off. and the station comes in clearly an instant after the power is turned on.
And the 6200 is always easily adaptable to your New SONY 6200 Stereo Receiver desires: You can elect to hear only stereo broadcasts. Or you can switch out the interstation muting to find the weak and distant stations normally hidden in the inter-station "hash" that muting eliminates (less than 3uV).
Even moderately noisy Mere() signals can be heard in stereo, thanks to a high-blend switch that reduces noise without affecting separation.
We could document all this performance with a host of specifications and graphs. But even these can merely indicate performance, not reveal it. The true revelation is your own listening experience, and the "ah" of your reaction to it. For many, that "ah!" will prevail over the "oh?" engendered by its price-converting that "oh?" perhaps to a Hmmm... With which, of course, your Sony dealer will be glad to harmonize. For if he, too, did not take pleasure in good sound, he would not be a Sony dealer. Sony Corporation of America, 47-47 Van Dam St., Long Island City, New York 11101.

When the Citation Twelve power amplifier was introduced, it was immediately hailed by HIGH FIDELITY magazine as . a virtually distortionless device.
- STEREO REVIEW said, ". . . the amplifier circuit. .
is disarmingly simple, yet it offers essentially state-of-the-art performance.- STEREO & HI-Fl TIMES summed it up by saying, "Harman-Kardon has produced an amplifier that is so close to theoretical perfection that it may be said that the Citation Twelve simply drops out of the reproduction chain. It simply produces no discernible sound of its own." Now Harman-Kardon presents the Citation Eleven, a superlative preamplifier worthy of the Citation name.
The Citation Eleven specifications are unmatched by any preamplifier ever made.
But specifications alone do not begin to convey the scope of this remarkable instrument.
For one thing, instead of conventional tone controls, the Citation Eleven employs a series of precision filters that permit you to boost or attenuate the signal at five critical points within the audio spectrum. By judicious use of the audio equalizer you can correct deficiencies in program material, speakers and room acoustics literally shaping your system's frequency response. What you actually hear is acoustically balanced to the requirements of your listening room.
But more. The Citation Eleven Citation Eleven (wired) $295.00 offers a full complement of professional controls, and enough inputs and outputs to satisfy the requirements of the most demanding audiophile. For example: two tape monitor switches; a front panel speaker selector switch for two sets of speakers; two low impedance headphone receptacles; a special defeat switch that removes the audio equalizer from the circuit for instant comparison of equalized and flat response.
The extraordinary performance and unparalleled flexibility of the Citation Eleven are unrivalled by any preamplifier on the market today.
To fully appreciate the Citation Eleven, you should hear it in combination with the Citation Twelve. But the Citation Eleven, in combination with any top flight amplifier, will provide unexcelled performance. Your Harman Kardon dealer will be happy to provide a demonstration.

THE GREAT SANSUI EIGHT: A NEW STANDARD OF EXCELLENCE
Some time ago, Sansui engineers were given a blank check. "Create the finest receiver in the world today," they were told. "Put in everything you ever wanted to see in your own equipment." And that's what they did. Today the Sansui EIGHT is a reality-the proudest achievement of a company renowned the world over as a leader in sound reproduction.
Take the features. Take the specs. Compare the Sansui EIGHT to anything you have ever seen or heard. Go to your franchised Sansui dealer today for a demonstration of the receiver that will become the standard of excellence by which others are judged. $499.95.
1 Ultrasensitive FM Front End Two RF amplifiers and one mixer amplifier use three costly, low-noise, dual-gated metal-oxide silicon field effect transistors (3 MOSFET's) and a 4-gang frequency-linear tuning capacitor. These combine to give the EIGHT its great edge in such areas as FM intermodulation distortion, sensitivity (1.7 microvolts IHF), signal-to-noise (better than 65 db) and image-frequency, IF and spurious-response rejection (all better than 100 db).
2 Three-IC IF Amplifier with Crystal/Block Filter
A three-stage differential amplifier, executed with integrated circuits, is combined with a sharply selective crystal filter and a block filter to give steep-sided response. This helps keep distortion very low (FM harmonic distortion is less than 0.5%), improves capture ratio (1.5 db) and stereo separation (better than 35 db at 400 Hz) and minimizes phase shift.
3 Sharp-Cut Multiplex Carrier Filter A two-stage LC sharp-cutoff filter really keeps the subcarrier out of the audio circuits. Where some leaks through, as in most FM receivers, you get increased intermodulation distortion and interference with the bias oscillator of tape recorders, which then mars all off-the-air home recordings.
4 FM Muting Switch and Adjuster
The switch cuts off all interstation hiss during tuning, if you wish. The level adjuster permits precise setting to cut off (or avoid cutting off) weak stations, as desired.
5 FM Linear-Scale Wide-Dial Design The linear scale is uniformly graduated in 250-kHz steps.
The blackout design features a smoked glass through which the dial shows only when the tuner is in use. The illuminated dial pointer also blacks out during non-use of the tuner.
6 Large Tuning Meters For pinpoint accuracy, one meter indicates signal strength (on FM or AM) while the other indicates exact FM center channel for minimum distortion and noise.
7 Dual Impedance Antenna Terminals The usual 300-ohm balanced antenna input, plus a 75-ohm unbalanced input for the coaxial cables used in remote or noisy areas, or in master-antenna distribution systems.
8 FET AM Tuner Most receiver designs ignore AM capability. The EIGHT uses two FET's along with a 3-gang tuning capacitor for high sensitivity and selectivity. A high-impedance antenna circuit also helps reduce interstation interference.
9 Unique Pantograph Antenna A dual swivel-arm mount, exclusive with Sansui, lets you draw the large AM bar antenna away from the chassis and orient for best reception, or fold it into the back panel to protect it against mishandling.
10 Smooth-Tuning Dial Pointer--A large fly wheel plus a precision nylon roar permit accurate, velvet-smooth tuning action and prevent slipping or jamming.
11. Three-Stage Equalizer Amplifier Emitter-to-emitter negative feedback is used in a three-stage amplifier realized with silicon transistors chosen for their low noise. The results: improved stability, excellent signal-to-noise ratio.
negligible distortion, high stability and extremely large dynamic range-it will handle cartridges with very high and very low output levels.
12 Multi-Deck Tape Capability
Two tape monitor circuits are brought out to a choice of pin-jack and 3-contact phone-type terminals on the front and rear panels. Play, record and monitor on either circuit. Or copy from one deck to the other via the Tape Monitor Switch.
13. Negative-Feedback Control Amplifier To minimize distortion, the tone-control circuit is driven by a two-stage circuit using both AC and DC negative feedback.
14. Triple Tone Controls Separate controls for bass, treble and midrange. And they're not the regular continuous controls Each is an 11-position switch carefully calibrated in db steps of boost and cut for the same adjustment precision used in studio work.
15. Sharp-Cut High and Low Filters Both high-and low-frequency filters use special transistors in emitter-follower negative-feedback circuits to provide sharp cutoff (12 db/octave).
16. Direct-Coupled Power Amplifier A two-stage differential amplifier is directly coupled to a complementary Darlington amplifier that uses no output capacitors and is driven by two power supplies, positive and negative. Negative feedback is uniformly effective at all frequencies, beyond the upper limits of audibility and down into the DC range-and the damping factor holds up very steadily down into the extremely low frequencies. The result: drastic reduction of intermodulation distortion not only in the amplifier itself, but in any speaker system connected to it.
17. Jumbo Filter Capacitors
Two enormous power-supply capacitors--8000 microfarads each--contribute to the extraordinary specifications of the EIGHT: 200 watts of IHF music power. 80 watts continuous power per channel. Distortion factor of 0.3% at rated output.
Power bandwidth of 10 to 40,000 Hz (at levels of normal use, way down to 5 Hz and up to 50,000 Hz, t1 db). Even when driven to maximum output, the EIGHT will deliver the clean est. most distortionless sound you have ever heard.
18. King-Size Heat Sink No overheating transistors even with continuous drive to maximum output.
19. Total Protection Extra transistors are used in a sophisticated circuit especially for temperature compensation. A special stabilizing circuit polices the differential amplifier. A power-limiting circuit and six quick-acting fuses protect the power transistors against overcurrent. And a completely separate circuit, using a silicon-controlled rectifier (SCR), safe guards your speakers against any possible damage.
20 Separable Pre- and Power Amplifiers Not only can the preamp and power amplifier be electrically separated, but the option can be used simply by flicking a front-panel switch.
Use them separately to connect electronic crossovers for speaker systems. Or separate them to use the preamp as a versatile control amplifier for tape recording o studio-type work while the power amplifier acts as a line or main amplifier.
21 Three-System Multi-Mode Speaker Capability Connect up to three speaker systems and switch-select any one or two different combinations of two. A special mode switch for one of these outputs permits it to drive two monophonic speakers for monitoring, or it can be used for a center-channel output.
22 Stereo Balance Check Circuit Turn on the Balance Check Switch and the tuning meter becomes a zero-center balance meter for precise matching of right and left channels.
23 Independent Power-Supply Circuits There's one each for the output stage, driver, control amplifier, head amplifier and tuner, with the last four separately stabilized to eliminate power fluctuation. This isolation blocks the interaction between one section and another that degrades performance in most integrated receivers. The Sansui EIGHT thus performs like a combination of separate tuner, control amplifier and power amplifier.
24 Plug-In-Board Functional Construction Each functional section is on its own printed-circuit board that plugs into the main chassis. This simplifies service-that is, if you should ever need service.
25 Mode Switches Flick a switch to change from stereo to mono. Flick another to choose between normal and reverse stereo.
26 Two Phono Inputs Accommodate two phonographs at the same time. or choose either input for ideal match to one cartridge.
27 Separate Input Level Adjusters Back-panel controls for FM and AM permit matching to level of phono output so that all functions reproduce at the same level for a given set ting of the volume control.
28 Quick-Connect Terminals Exclusive push button, foolproof terminals grip connecting leads for antennas and speakers. No fumbling with screwdrivers and wire twisting. Just in ser-. wire end and release.
29 Universal Supply-Voltage Adaptability A changeover socket for power-supply input voltage adjusts to eight different a-c supply-
source levels. for use anywhere in the world.
30 Detachable AC Line Cord 31 Program Indicators Illuminated legends on a dark background indicate all selected functions except AM and FM. For the latter two, the tuning dial and pointer also light up.
32 FM Stereo Indicator Illuminated legend lets you know when the FM source is transmitting in stereo, even when you've selected FM mono.
33 Integral Walnut Cabinet No need for a separate cabinet. The EIGHT comes inside its own furniture-finished walnut cabinet. And it has legs that can be adjusted for a custom fit to the shelf or other furniture on which it is placed.

Because of their exceptional accuracy, Acoustic Research speaker systems are usually chosen for special scientific applications.
One of the world's leading medical schools has recently solved a long-standing problem in its training of first-year students: how to enable a lecturer and hundreds of listeners to hear simultaneously the heart sounds of a living patient.
Usable microphonic pickups exist; the difficulty arises because most of the sound in a heartbeat is in the range below 40 Hz. At these very low frequencies. even many speaker systems which seem to have "good bass" are unable to provide results comparable to those of a doctor's stethoscope. The stethoscope, simple as it is, couples the physician's ears directly to the patient's chest, and can, in principle. convey acoustic pulses near 0 Hz. It is this kind of extended low-frequency response which was needed. but individual listening devices were out of the question; they would not allow lecturer and students to hear and recognize the same abnormalities without ambiguity.
The problem was solved by the school's purchase of four standard full-range AR-lx speaker systems and an AR amplifier;
the latter is used with all controls "flat". Despite the large size of the lecture hall. the heart sounds are clearly audible to all students. and levels can be produced which literally rattle the doors and windows of the amphitheater.
Our best system for music reproduction is our AR-3a; it has the same low-frequency characteristics as the AR-1x, but includes our most accurate mid-range and high-frequency drivers also. Other AR speaker systems are described in the free AR catalog.

From any place in the room, the versatile Achromatic W35 is a top per former... built to take power and give it all back ... with ease! The unique shape permits shell use in two ways:
either straight-on; or at the acoustically desirable but frequently wasted corners. And, with an optional corner mounting bracket, suspension in room corners becomes both simple and decorative.
The robust, extraordinary performance of the W35, despite its modest size (15" x 15" x 8" deep), is a result of its being a full 3-way speaker sys tem and of its professional quality components. The 8" woofer is a heavy duty, long-throw assembly with over sized, four layer-wound voice coil for maximum heat dissipation and fully controlled transient response. A 31/4" acoustically isolated midrange unit covers this important spectrum with clarity and definition; while a 21/2" ultra-curvilinear tweeter with low mass aluminum voice coil provides treble tones that faithfully image the original. A multi-element LCR net work reduces electrical and acoustical distortion. Cabinet buzzes and resonances are avoided by sturdy, "unitized" construction.
One of six Wharfedale speaker systems engineered to satisfy every budget. space and performance requirement, the W35 is compellingly priced at $82.00 list.

And that's a simple statement of fact. From the moment it was introduced, the Revox A77 was hailed as a recording instrument of unique quality and outstanding performance. The magazines were unanimous in their praise. Stereo Review summed it all up by saying, "We have never seen a recorder that could match the performance of the Revox A77 in all respects, and very few that even come close." So much for critical opinion.
Of equal significance, is the fact that the Revox A77 rapidly found its way into many professional recording studios.
But what really fascinates us, is that the A77 has been singled out to perform some unusual and highly prestigious jobs in government and industry. The kinds of jobs that require a high order of accuracy and extreme reliability.
Take NATO (the North Atlantic Treaty Organization) for example.
When they wanted a machine to standardize on, a machine that would lend itself to use in a wide variety of circum stances and most importantly, a machine that was simple to use, the logical choice was the Revox A77.
Or take the governmental agency that wanted an unfailingly reliable tape machine to register and record satellite bleeps. The choice? Revox.
Or the medical centers that use specially adapted A77's for electro cardiographic recording.
We could go on and on (see accompanying list), but by now you probably get the point.
No other 1/4" tape machine combines the multi-functioned practicability, unfailing reliability, and outstanding performance of a Revox.
If you have a special recording problem that involves the use of 1/4" tape, write to us. We'll be happy to help you with it.
And if all you want is the best and most versatile recorder for home use, we'll be glad to tell you more about that too.

THE RECORD LOVERHATER
The job of the music critic isn't easy. He can help a record make it to the top or damn it to oblivion.
And since many people depend on his judgment when they shop for records, it's logical to ask:
"But what does he depend on?" Mostly, his ears and his knowledge help him as he listens. Yet the music critic can only hear what his stereo system delivers. If his critical listening is to be unbiased, it must begin with a stereo cartridge whose frequency response characteristics are as flat as possible. One that introduces no extraneous coloration as it reproduces recorded material.
Many record critics do their auditioning with the Stanton 681EE. Recording engineers have long used the Stanton 681A to check recording channel calibration.
The 681EE provides that logical continuation of the Stanton Calibration Concept. It has been designed for Edward Tatnall Canby, Author and Critic low-distortion tracking with minimum stylus force. Its low-mass, moving magnetic system produces virtually straight-line frequency response across the entire audio spectrum. Its built-in longhair brush keeps the stylus dust-free, and protects record grooves, thus reducing noise and wear. Each 681EE is individually calibrated, and the results of these calibration tests are included with each cartridge.
The Stanton 681EE-used by recording engineers, broadcasters, critics and audio professionals-the cartridge that sounds like the record sounds, always.

Only one man on earth understands "Pri Selon Pli" as well as the man who wrote it.
And that's the man who conducts "Pli Sebn Pli," by Pierre Boulez, is probably his most complex (and rewarding) work.
Not nanny men are capable of conducting it authoritatively. (Or even of understanding it completely.) We quote from The Gramophone "The work's constant shifting on several levels simultaneously is suggestive of a labyrinth wherein colors, motions, shapes are endlessly transformed." In fact, there's only one conductor capable of doing this work justice.
His name is Pierre Boulez and as de from the obvious advantages of having a composer conduct his own work, ware happy He did it for another reason as well.
Conducting this work is an extremely difficult task. But we knew he wouldn’t complain. On Columbia Records It.

We invited 2 generations to play for Beethoven's 200 th anniversary.
For this auspicious date, we offer two milestone albums. The dream quartet for The Triple Concerto:
Rostropovich, Oistrakh, Richter, and Karajan, with the Berlin Philharmonic.
This marks the first time these four dazzling talents have ever been brought together. That alone makes this album very special. But the music makes it monumental. In an era of over-duplication, the Triple has been under-recorded.
You will seldom hear music of such sublimity. Here are three of history's greatest soloists, at the height of their artistic maturity.
And throughout, Karajan fuses their incomparable talents into a recording triumph.
The second milestone : The Piano Trios, with Daniel Barenboim, piano ; Pinchas Zukerman, violin ; Jacqueline du Pre, cello three of the most vital and exuberant artists of our day. Combine their ages and you get 75.
Combine their talents and you get breathtaking music, suffused with ageless beauty.
The album contains five records. In the Clarinet Trio, Gervase de Peyer's liquid tone meshes impeccably with cello and piano. An altogether inspired and thrilling listening experience.
Both albums make spectacular gifts. To yourself. To a valued friend. To the memory of the man who composed it all.

you'll see how gently the Miracord 50H treats your records.
A gentle touch of the push buttons brings forth a gentle reaction from the Miracord 50H. The dynamically balanced arm responds gently with its frictionless bearing system, faithfully and flawlessly tracking the intricate record grooves. Gentleness, however, is just one attribute of the 50H, a clue to its superior performance is found in its features.
Stylus overhang adjustment is essential for optimum tracking. Another automatic turntable does feature this adjustment, but it's internal and difficult to set.
The Miracord 50H offers external over hang adjustment with built-in gauge no shifting, no guesswork, no templates.
Other turntables offer a kind of synchronous motor. The 50H uses a Papst hysteresis asynchronous motor with outer rotor for unvarying speed accuracy regardless of the voltage fluctuation or loads. The Papst motor is usually found in professional studios.
Consider cueing: in one leading automatic turntable, cueing does not operate in the automatic mode. In automatic, cueing is the ideal way to interrupt play for a moment when there is a stack of records on the spindle. The 50H pro vides silicone-damped cueing in both automatic and manual modes.
Miracord 50H Another important feature is the 50H turntable. It is a heavy, one-piece, non-ferrous metal casting, lathe-turned to precise dimensions and then individually dynamically balanced. This contributes to the smooth, steady motion of the turn table, free of rumble, wow and flutter.
Nothing we can say short of experiencing it yourself can better describe the 'gentle way in which the Miracord responds and preserves the best in your records. Find out for yourself. Miracord 50H. $175 less cartridge and base.
Miracord feather-touch automatic turn tables start at less than $100. Benjamin Electronic Sound Corporation, Farmingdale, N.Y. 11735/a div. of ISC/available in Canada.

This deck is powered by a unique hysteresis synchronous outer rotor motor for compact convenience, powerhouse performance. And it comes complete with all the craftsmanship It takes to make a TEAC.
More exclusive features: a special end-of-tape sensing circuit which rot only stops the cassette, but completely disengages the mechanism--releasing pushbuttons, pinch roller and idlers-to avoid "flats" and deformation of critical drive components. Two specially-designed heads for outstanding frequency response. Just about the lowest wow and flutter that ever came out of a cassette.
